FUNCTIONAL DEVICES AND LIGHTING DEVICE

Description

[0001] The present invention relates to a functional module with functional devices that have at least one motion, presence and / or brightness sensor, at least one luminaire or luminaire driver control device and at least one wireless communication device and that are coupled or can be coupled to at least one LED and / or one LED driver.

[0002] Furthermore, the present invention relates to a lighting device with at least one LED, one LED driver and functional devices which have at least one motion, presence and / or brightness sensor, at least one luminaire or luminaire driver control device and at least one wireless communication device and which are coupled or can be coupled to at least one LED and / or one LED driver.

[0003] Luminaires are increasingly being integrated with various functional devices to enhance functionality while allowing users to create customized lighting scenes. Luminaires can include, among other components: at least one illuminant, such as an LED board, an LED driver for controlling the at least one illuminant and for converting the mains voltage, motion and brightness sensors for detecting the presence of persons and ambient brightness, and a control device for controlling the at least one illuminant, e.g., for integrating the luminaire into a lighting control system, for wireless communication of the luminaire with other luminaires, and / or for controlling application-specific lighting scenes.

[0004] In the luminaires known from the state of the art, these different functional devices are integrated into the respective luminaire as independent devices with their own power supply and housing. The individual functional devices are connected via standard interfaces, such as DALI (Digital Addressable Lighting Interface), SR (Sensor Ready), I2C (Inter-Integrated Circuit), or 1-10V. Due to the large number of different functional devices with their own power supply and housing that must be integrated into a luminaire, the installation of such a luminaire is very complex, particularly due to the attachment of the individual functional devices inside the luminaire and the wiring of the individual functional devices to one another.In addition, when installing such a luminaire, there is a risk that individual functional devices may be incorrectly wired together, or that the wiring between individual functional devices may break or tear off a circuit board. Placing and securing the various functional devices inside the luminaire can also be difficult. Furthermore, the placement of the individual functional devices and their electrical wiring requires a relatively large amount of space.

[0005] US 2011 / 0193491 A1 discloses a driver device for an LED lighting device. The driver device includes, among other things, a controller, a light sensor, a presence sensor, and a remote control. All elements of the driver device are integrated into a substrate.

[0006] The document DE 203 09 033 U1 describes a lighting module which comprises LED semiconductor chips, sensors applied to a Peltier element and control and evaluation electronics which are applied to a metal or ceramic base.

[0007] It is therefore the object of the present invention to improve the functionality of lighting devices while reducing their assembly effort and optimizing their size.

[0008] The object is achieved, on the one hand, by a functional module with functional devices which have at least one motion, presence and / or brightness sensor, at least one luminaire and / or luminaire driver control device and at least one wireless communication device and which are coupled or can be coupled to at least one LED and / or one LED driver, wherein the functional devices, i.e. at least the at least one motion, presence and / or brightness sensor, the at least one luminaire and / or luminaire driver control device and the at least one wireless communication device, are combined on a single module board to form the single functional module which is designed as an SMD or THT component and is configured such that it is suitable for mounting on a carrier board, wherein the luminaire and / or luminaire driver control device is a microcontroller of the wireless communication device.

[0009] The functional module is an intelligent sensor module.

[0010] By combining the at least one motion, presence, and / or brightness sensor, the at least one luminaire control device and / or luminaire driver control device, and the at least one wireless communication device on the module board to form the functional module, assembly, in particular the wiring effort, is greatly simplified when manufacturing LED-based lighting devices. The functional module provides essential functions of the respective lighting device within a single module, which can be used for different lighting devices. This results in high functionality of the respective lighting device while simultaneously ensuring high functional reliability.

[0011] The functional devices of the functional module, which are combined on the module board, are preferably arranged in predetermined positions on the module board and electrically coupled to one another by conductor tracks provided on the module board. The module board itself, in turn, has suitable electrical connection elements with which it can be attached to the carrier board, which also houses the at least one LED and the LED driver. Accordingly, the use of the functional module allows for the production of lighting devices with high functionality relatively easily, quickly, and cost-effectively. The risk of incorrect wiring of the individual functional devices, a cable break, or a tearing of an electrical connection is also avoided by using the module board with its highly stable conductor tracks.

[0012] For particularly simple and quick installation of the functional module in a lighting arrangement, the module board of the functional module is ideally designed as an SMD (surface-mounted device) or THT (through-hole technology) component. If the functional module is designed as an SMD component, the module board has solder pads that serve to secure it to a carrier board and can be easily processed using an automatic SMD assembly machine. The solder pads for securing the functional module to the carrier board can alternatively be arranged on a shield or on a connecting element.Insofar as the functional module is designed as a THT component, which can also be referred to as a through-hole technology component, the module board either has solder pins which are used for assembly on a carrier board having through-holes, or the module board has through-holes into which solder pins provided on the carrier board can engage.

[0013] The luminaire and / or luminaire driver control device is a microcontroller of the wireless communication device. If the wireless communication device has a Bluetooth module, the Bluetooth chip can be used as the microcontroller.

[0014] In alternative design variants of the functional module, the module board can also be equipped with printed circuit board connectors. When using printed circuit board connectors, flat printed circuit board connectors are preferably provided on the module board, with counterparts to the printed circuit board connectors being attached to a carrier board to be coupled to the module board.

[0015] The functional module contains all essential components required to control a lighting device. The functional module has a motion or presence sensor for detecting the presence of persons and / or a brightness sensor for detecting ambient brightness in order to be able to control at least one lighting device depending on the presence of persons and / or the ambient light on the basis of the respectively detected signals, a wireless communication device for operating and adjusting at least one lighting device and / or the lighting or lighting driver control device, for example with the aid of a smartphone or the like, and if necessary for networking a lighting device with other lights and / or components of a building control system, as well as an interface to a carrier board produced by the lighting and / or lighting driver control device.

[0016] In the present invention, the carrier board is understood to be the board that is equipped with the functional module using the module board.

[0017] The functional devices mounted on the module board, i.e. at least the at least one motion, presence and / or brightness sensor, the luminaire and / or luminaire driver control device and the wireless communication device, are preferably coupled to one another by means of conductor tracks provided on the module board, but can also be coupled to one another at least partially wirelessly.

[0018] The wireless communication device of the functional module preferably comprises a Bluetooth module or a Bluetooth chip, which has Bluetooth mesh radio technology (Bluetooth network radio technology) and / or BLE (Bluetooth Low Energy) radio technology (Bluetooth energy-saving radio technology). By using Bluetooth mesh radio technology, various Bluetooth-enabled devices can be coupled with one another. By using BLE radio technology, i.e., a power-saving version of Bluetooth, a point-to-point connection, such as a connection between the functional module and a smartphone, can be established even without Bluetooth mesh. It has also proven advantageous if the Bluetooth module is designed as an SoC (System on Chip).In alternative variants of the functional module, the wireless communication device may support another communication standard, such as Zigbee or Thread, and / or a WLAN and / or infrared-based communication device instead of Bluetooth or in addition to or in combination with it.

[0019] Advantageously, the functional module has at least one motion, presence and / or brightness sensor, but can also have at least one motion or presence sensor or at least one brightness sensor. The at least one motion or presence sensor detects movements and / or the presence of people, animals or objects in a detection area and, as a result, a lamp of a lighting device which has the functional module is activated or deactivated or its luminosity is changed, i.e. dimmed. This allows the lighting device to be operated in an energy-saving manner. The at least one brightness sensor measures or detects the brightness in the environment. If a specified brightness value is exceeded or undershot, a lamp is activated or deactivated, whereby the activation or deactivationDeactivation can be made dependent on the sensor data of the motion sensor if at least one motion sensor is present.

[0020] Alternatively, the at least one brightness sensor can be used to regulate the luminous flux of at least one light source depending on the ambient light so that a desired illuminance is always ensured by the at least one light source. When ambient light is sufficient, the luminous flux of the at least one light source and thus its energy consumption can be reduced, which can also be described as "daylight harvesting."

[0021] The luminaire and / or luminaire driver control device of the functional module serves to control at least one luminaire, such as at least one LED, wherein the luminaire and / or luminaire driver control device enables integration into a lighting control system, wireless communication with other luminaires, control of application-specific lighting scenes and application of motion, presence and / or brightness sensors.

[0022] In a favorable embodiment of the invention, the functional module is integrated into an LED driver, or an LED driver is a component of the functional module. If the functional module is integrated into the LED driver, the LED driver provides the most important functions required for a lighting device. Since the functional devices are combined in the functional module according to the invention, this can be integrated into the LED driver relatively easily.

[0023] In alternative embodiments of the invention, however, the functional module can also be integrated into a sensor with its own power supply and relay or DALI (Digital Addressable Lighting Interface) interface or another interface.

[0024] Particularly preferably, electronic components of the functional module, including the at least one luminaire and / or luminaire driver control device, are mounted on a rear side of the module board.

[0025] Preferably, at least one antenna of the wireless communication device and / or at least one antenna of a motion or presence sensor and / or a brightness sensor of the at least one motion, presence, and / or brightness sensor are arranged on a front side of the module board. In this embodiment of the invention, the wireless communication device is also coupled to the at least one motion, presence, and / or brightness sensor.

[0026] Alternatively, the brightness sensor can also be arranged in a different position, such as on the back of the module board, whereby daylight can hit the brightness sensor, for example, through a hole in the module board.

[0027] Alternatively, the antenna of the wireless communication device can also be arranged at a different position, such as on the back of the module board.

[0028] For cost reasons, the use of a conductor antenna, such as a λ / 4 or F antenna, has proven to be advantageous as the antenna of the wireless communication device. Alternatively, a chip antenna or other antenna can also be used.

[0029] In a further embodiment of the invention, all electronic components arranged on the module board, such as the motion or presence sensor, the antenna of the motion or presence sensor, the wireless communication device, the luminaire and / or luminaire driver control device, the brightness sensor and the antenna of the wireless communication device, are applied to the front side of the module board.

[0030] With regard to the size of the functional module and its placement in a lighting device, it has proven advantageous for the functional module to have a maximum module area of ​​10 cm². A module area is defined as the area of ​​the functional module as seen from above when mounted on the carrier board. With a maximum module area of ​​10 cm², the functional module is only slightly larger than an RF sensor module, which typically has dimensions of 33 x 23 x 5 mm.

[0031] Additionally, it is advantageous if the microcontroller is connected to the at least one motion, presence, and / or brightness sensor and has a sensor data processing module. This allows the functional module comprising the individual functional devices to be provided cost-effectively and with minimal control effort. The microcontroller processes the analog sensor signals of the at least one motion, presence, and / or brightness sensor.

[0032] In further variants of the functional module, however, it can also have more than one microcontroller. For example, the at least one wireless communication device and / or the at least one motion, presence, and / or brightness sensor can be operated by separate microcontrollers.

[0033] For simple assembly and the smallest possible space requirement of the functional module, it has also proven advantageous if the functional module does not have a power supply or batteries. In such embodiments, the functional module or the functional devices of the functional module are advantageously supplied with a direct voltage or direct current by the carrier board.

[0034] Furthermore, with regard to assembly and space requirements of the functional module, it is advantageous if the functional module itself does not have a housing or any power electronic or electromechanical components, such as relays, for directly controlling or switching the at least one LED. Such components can be provided separately on the carrier board or are not required if, for example, a digital interface (such as DALI) or another control signal is used to control the LED driver.

[0035] In a simple embodiment of the present invention, it is also possible, for example, for the functional module to use a pulse-width modulated (PWM) signal to control a light source, such as at least one LED. In this case, the brightness of the light source on the carrier board can be controlled and switched on and off using only power electronic components, such as at least one switching transistor, and without additional control components.

[0036] In possible embodiments of the functional module, the at least one motion, presence, and / or brightness sensor comprises at least one RF sensor that emits electromagnetic waves at a frequency of 5.8 GHz, 24 GHz, 61 GHz, or 120 GHz. The RF sensor is used to detect movement and thus activate an LED. For example, the RF sensor registers a frequency shift in the RF radiation reflected by a moving object, utilizing the Doppler effect. Alternatively, other RF sensor methods can be used that, in addition to or as an alternative to motion detection, can detect distance, angle, or 3D positions in space. Examples include FMCW, FSK, MIMO, and others. Upon detection of movement and / or changes in the echo image, the RF sensor activates a light. The use of a low-frequency RF sensor, such as 5.8 GHz, results in a comparatively cost-effective functional module.If, however, an RF sensor with a higher frequency, such as 61 GHz or 120 GHz, is used, the size of the at least one motion, presence, and / or brightness sensor, and thus also of the functional module, can be reduced. In alternative embodiments of the functional module, other sensors, such as at least one infrared sensor, can be used instead of an RF sensor.

[0037] In an advantageous embodiment of the present invention, the at least one motion, presence, and / or brightness sensor is mounted on at least one baseboard with which the module board is equipped. Mounting the at least one motion, presence, and / or brightness sensor on the baseboard enables quick and cost-effective placement of these component(s) on the module board. The at least one motion, presence, and / or brightness sensor can be mounted on the module board as a separate module by arranging it on the at least one baseboard, thereby reducing the manufacturing costs of the functional module. By using the baseboard, the module board can be manufactured from a cost-effective material and / or with small dimensions.Furthermore, mounting the motion, presence, and / or brightness sensor on the baseboard also increases the flexibility of the functional module, as various functional devices can be easily arranged on the module board. Particularly preferably, at least the motion or presence sensor and its at least one antenna are mounted on the baseboard.

[0038] The object is further achieved by a lighting device with at least one LED, an LED driver and functional devices according to the invention.

[0039] In an advantageous embodiment of this lighting device, at least the at least one LED is mounted on the same carrier board as the functional module.

[0040] In a further advantageous embodiment of the lighting device according to the invention, the LED driver is also mounted on the carrier board.

[0041] The lighting device according to the invention therefore has, in addition to the at least one LED and the LED driver, the functional devices combined to form the functional module.

[0042] Preferably, at least one LED and the functional module are mounted on the same carrier board and are electrically connected to one another in a functionally appropriate manner.

[0043] However, it is also possible in the lighting device according to the invention for the functional module to be installed in the LED driver or in a sensor of the at least one motion, presence and / or brightness sensor, wherein in this embodiment of the invention the functional module is not mounted on the same carrier board as the at least one LED.

[0044] In a simple embodiment of the present invention, the lighting device consists of only four components, namely a carrier board, at least one LED mounted thereon, an associated LED driver mounted on the carrier board or provided separately, and a functional module likewise mounted on the carrier board, which contains at least one motion, presence, and / or brightness sensor, at least one luminaire and / or luminaire driver control device, and at least one wireless communication device, all of which are mounted on a single module board. The lighting device can thus be manufactured cost-effectively and with comparatively little assembly effort. To form such a lighting device, it is only necessary to equip the carrier board with the at least one LED, the LED driver, and the functional module.Corresponding wiring, through which the at least one LED, the LED driver, and the functional devices of the functional module are electrically and thus functionally connected to one another, can preferably already be present on the carrier board. In addition to significantly simplifying and accelerating the assembly process, the use of the functional module during lighting device assembly can significantly minimize the risk of incorrect wiring of the individual functional devices and the risk of damage to individual connections.

[0045] In the present invention, an LED driver is understood to be a ballast for controlling at least one LED and converting the mains voltage into direct current or voltage.

[0046] The embodiments shown in the figures do not fall under the wording of the claims, but are considered to facilitate the understanding of the invention. Figure 1 schematically shows an embodiment of a lighting device with a functional module in a side view; Figure 2 schematically shows a further embodiment of a lighting device with a functional module in a side view; Figure 3 schematically shows the function of a functional module according to an embodiment; Figure 4 schematically shows the function of a carrier board with an LED driver and a functional module according to an embodiment; Figure 5 schematically shows the function of an LED driver with an integrated functional module according to an embodiment; Figure 6 schematically shows the integration of a functional module according to an embodiment into a sensor; Figure 7 schematically shows a further embodiment of a lighting device with a functional module in a side view; Figure 8 schematically shows yet another embodiment of a lighting device with a functional module in a side view;and Figure 9 schematically shows yet another embodiment of a lighting device with a functional module in a side view. ;

[0047] Figure 1 shows a schematic side view of an embodiment of a lighting device 1 with a functional module 9. The lighting device 1 has a carrier board 2, on which an LED 3, an LED driver 4, and the functional module 9 are applied and mounted. Instead of the single LED 3, a plurality of LEDs 3 can also be used. Preferably, the LED driver 4 then serves to control all LEDs 3, but multiple LED drivers 4 can also be provided on the carrier board 2.

[0048] LED 3 serves as the light source. LED driver 4 is connected upstream of LED 3 and electrically connected to it. LED driver 4 serves to regulate the current flow of a power grid, converting the alternating current of the power grid to a constant, low direct current, which powers LED 3.

[0049] In the embodiment of Figure 1 The LED driver 4 is mounted together with the LED 3 on the carrier board 2. The LED 3 is coupled to the LED driver 4 by means of at least one conductor track 12 mounted on the carrier board 2. Alternatively, the LED driver 4 can also be located on a separate board, i.e., not on the carrier board 2, in which case the separate board is electrically coupled to the carrier board 2.

[0050] Function module 9 has the following Figure 1The embodiment shown has a module board 8, on the rear side B of which certain electronic components of the functional module 9, such as a motion or presence sensor 52, a wireless communication device 7, and a luminaire and / or luminaire driver control device 6, are mounted, while an antenna 52a of the motion or presence sensor 52, a brightness sensor 51, and an antenna 7a of the wireless communication device 7 are provided on a front side A of the module board 8. Instead of the brightness sensor 51 shown purely as an example, a plurality of brightness sensors 51 can be provided on the front side A of the module board 8. Likewise, a plurality of antennas 7a of the wireless communication device 7 and / or a plurality of antennas 52a of motion or presence sensors 52 can also be provided on the front side of the module board 8.

[0051] The motion or presence sensor 52, the brightness sensor 51, the luminaire and / or luminaire driver control device 6 and the wireless communication device 7 are connected to one another by conductor tracks not shown here, but can also be connected to one another at least partially wirelessly.

[0052] The electronic components on the module board 8 are at least partially enclosed by a shield 14. The shield 14 meets the EMC requirements of the EU directives and comparable regulations in other markets. The shield 14 can be made of sheet metal or printed circuit board material, for example.

[0053] The module board 8 is electrically connected to the carrier board 2 via at least one electrical connection 15. The at least one electrical connection 15 serves to supply power to the functional module 9 and to electrically connect the luminaire and / or luminaire driver control device 6 to the LED driver 4. The at least one electrical connection 15 can be technically implemented by SMD pads on the shield 14, by SMD pads on the module board 8, by solder pins, and / or by printed circuit board connectors.

[0054] By combining the motion or presence sensor 52, the brightness sensor 51, the luminaire and / or luminaire driver control device 6, and the wireless communication device 7 on the module board 8 in the form of the functional module 9, the lighting device 1 can be designed with minimal assembly and electronics effort, while also being cost-effective. Advantageously, the functional module 9 designed in this way can be applied to different boards, such as the carrier board 2, with little effort to provide functions for different lighting devices, such as LEDs.

[0055] In the embodiment shown, the functional module 9 is designed as an SMD component and placed on the carrier board 2.

[0056] In alternative embodiments of the lighting device 1, however, the functional module 9 can also be designed differently and attached to the carrier board 2. For example, the functional module 9 can be configured as a THT component, wherein the module board 8 has solder pins that serve for assembly on the carrier board 2. Furthermore, printed circuit board connectors can also be used to attach the functional module 9 to the carrier board 2. In this case, the module board 8 of the functional module 9 is provided with flat printed circuit board connectors, with counterparts to the printed circuit board connectors located on the carrier board 2.

[0057] The module board 8 is electrically coupled to the LED driver 4 by at least one conductor track 11. The LED driver 4, in turn, is connected to the LED 3 by at least one conductor track 12.

[0058] The power supply of the functional module 9 or the individual power-requiring functional devices of the functional module 9, such as the motion or presence sensor 52, the brightness sensor 51, the luminaire and / or luminaire driver control device 6, and the wireless communication device 7, is realized via a power source (not shown here) mounted on the carrier board 2. For example, the LED driver 4 can serve as the power source.

[0059] In the illustrated embodiment, the wireless communication device 7 has a Bluetooth module or a Bluetooth chip for communication with a user. Using the Bluetooth module or chip, the respective user can control the lighting device 1, for example, using a smartphone. The Bluetooth module or the Bluetooth chip uses Bluetooth Mesh radio technology and BLE radio technology. BLE radio technology enables data transmission with low energy consumption. Bluetooth Mesh is a wireless communication technology based on the BLE communication protocol and can be used optionally. With Bluetooth Mesh, communication can be established between many different devices, such as different lights or other building control products. Data transmission also works if the device that originally sent a message is not within direct radio range.Furthermore, the use of Bluetooth mesh enables communication between devices from different manufacturers.

[0060] The luminaire and / or luminaire driver control device 6 is used to control the LED 3, to integrate the lighting device 1 into a lighting control system, to communicate wirelessly with other luminaires and / or a smartphone or similar, and to control application-specific lighting scenes.

[0061] The motion or presence sensor 52 and the brightness sensor 51 are used to control the LED 3 depending on the presence of people and the ambient brightness. The motion or presence sensor 52 is an RF sensor. In the illustrated embodiment, a 5.8 GHz sensor is used as the RF sensor. Alternatively, RF sensors with a higher frequency can also be used, which allows the size of the functional module 9 to be reduced.

[0062] Figure 2shows schematically a further embodiment of a lighting device 1' with a functional module 9' in a side view, wherein the same reference numerals as in Figure 1 refer to the same or similar elements, which is why, to avoid repetition, reference is made to the above explanations regarding these elements.

[0063] Unlike in the Figure 1 In the embodiment of the lighting device 1 shown in the drawing, the lighting device 1' is Figure 2 The functional module 9' is integrated into an LED driver 4'. The LED driver 4' thus contains all the functions required for a lighting device with the exception of an LED 3. Advantageously, such an LED driver 4' can be flexibly combined with a wide variety of light sources and designs of LED-equipped circuit boards.

[0064] The functional module 9' integrated into the LED driver 4' is mounted on a carrier board 2 by means of a module board 8', on which the LED driver 4' is also mounted. The module board 8' is electrically connected to the LED 3 by at least one conductor track 11 applied to the carrier board 2. In other variants of the lighting device 1', it can also have more than one LED 3.

[0065] Also with the lighting device 1' of Figure 2 The wireless communication device 7 has an antenna 7a provided on a front side A of the module board 8'. Furthermore, the antenna 52a of a motion or presence sensor 52 arranged on the back side B of the module board 8' and a brightness sensor 51 are also provided on the front side of the module board 8'.

[0066] While the front side A of the module board 8' serves for interaction with the environment, the associated electronic components, such as the motion or presence sensor 52 as well as a Bluetooth chip of the wireless communication device 7, are provided on the back side B of the module board 8'.

[0067] For cost reasons, the Figure 2 In the embodiment shown, conductor antennas are used as antennas 7a, 52a. Alternatively, however, at least one chip antenna or another antenna can also be used. A chip antenna can be used, for example, if a conductor antenna cannot be used due to space or performance constraints.

[0068] The module board 8' is electrically connected to electrical conductors 11 on the carrier board 2 via at least one electrical connection 15. The module board 8' is coupled to the LED 3 via the carrier board 2.

[0069] Figure 3shows schematically the function of a functional module 9. The Figure 3 The functional module 9 shown has a connection 500 for a supply voltage, a microcontroller 60, a brightness sensor 51, a motion or presence sensor 52, a wireless communication device 7 with Bluetooth module 71 and an interface 30 to an LED 3 not shown here.

[0070] The connection 500 is electrically connected to a power source 50 on the one hand, and to the microcontroller 60, the brightness sensor 51, the motion or presence sensor 52, and the Bluetooth module or chip 71 on the other. To control the LED 3, the microcontroller 60 is further coupled to the sensors 51, 52, the wireless communication device 7, and the interface 30. The interface 30 forwards the signals from the microcontroller 60 to a switching device 31, designed as a relay, which is connected to the LED 3 (not shown here).

[0071] The Figure 3 The functional module 9 shown advantageously combines all the functional devices required for controlling an LED 3 as a unit. However, the functional module 9 shown does not have its own power source, housing, or power electronic or electromechanical components for directly controlling or switching a light source. In further embodiments of the functional module 9, however, it can also have a power source and / or a housing and / or at least one power electronic or electromechanical component.

[0072] Figure 4 shows schematically the function of a carrier board 2 with an LED driver 4 and a function module 9. In the Figure 4In the embodiment shown, in addition to the functional module 9, a power source 50, an LED driver 4, and an LED 3 are mounted on the carrier board 2. When using a carrier board 2 configured in this way, a lighting device would only comprise the carrier board 2 with the components mounted on it. Optionally, however, the LED driver 4 can also be incorporated into a lighting device separately from the carrier board 2 equipped with the functional module 9 and the power source 50.

[0073] The functional module 9 of Figure 4 essentially corresponds to functional module 9 of Figure 3 , where the functional module 9 of Figure 4is not coupled to a switching device 31, but rather to the LED driver 4. The LED driver 4, in turn, is electrically connected to the LED 3 for controlling it. Like the power supply to the functional module 9, the LED driver 4 is supplied with power by the power source 50, which has a mains connection 501.

[0074] Figure 5 shows schematically the function of an LED driver 4' with integrated function module 9. In contrast to the embodiment of Figure 4The LED 3 is provided here on a separate circuit board, which is coupled to the LED driver 4' via connection 20. In this embodiment, the coupling is via a cable, but can also be implemented via a conductor track or in another way. In this embodiment, the LED driver 4' provides several different functions required for a lighting device. Advantageously, such an LED driver 4' can be flexibly combined with a wide variety of lighting sources.

[0075] Figure 6 shows schematically the integration of a functional module 9 into a sensor 80 with its own power source 50 and switching device 31 designed as a relay.

[0076] Figure 7 shows schematically a further embodiment of a lighting device 1" with a functional module 9 in a side view. Unlike in the Figures 1 and 2 are located at the lighting device 1" from Figure 7all electronic components mounted on the module board 8 on a front side A of the module board 8. In this case, the wireless communication device 7, the antenna 7a of the wireless communication device 7, the luminaire and / or luminaire driver control device 6, the motion or presence sensor 52, the antenna 52a of the motion or presence sensor 52 and the brightness sensor 51 are arranged on the front side A of the module board 8, whereas there are no electronic components on a rear side B of the module board 8.

[0077] In the Figure 7In the embodiment shown, the lighting device 1" does not have a shield 14 surrounding the electronic components placed on the module board 8. By applying the electronic components to the front side A of the module board 8 and the associated omission of the shield 14, the lighting device 1" can be manufactured comparatively cost-effectively. In alternative embodiments of the lighting device 1", the electronic components applied to the front side A of the module board 8 can also be at least partially surrounded by a shield.

[0078] The module board 8, unlike in the Figures 1 and 2In the embodiments shown, the module board 8 is not electrically connected to the carrier board 2 via an electrical connection 15, for example in the form of a plug, but rather via an SMD solder connection. For this purpose, the module board 8 has SMD pads 81, which simultaneously serve to secure the module board 8 to the carrier board 2 and to electrically connect the module board 8 to the carrier board 2.

[0079] Figure 8 shows schematically yet another embodiment of a lighting device 1‴ with a functional module 8 in a side view.

[0080] The functional module 9 of the lighting device 1‴ of Figure 8has a module board 8, on the rear side B of which certain electronic components of the functional module 9, such as the wireless communication device 7 and the luminaire and / or luminaire driver control device 6, are mounted. The motion and / or presence sensor 52, the antenna 52a of the motion or presence sensor 52, the brightness sensor 51, and the antenna 7a of the wireless communication device 7 are provided on the front side A of the module board 8.

[0081] In the case of the lighting device 1‴ of Figure 8 The motion or presence sensor 52 and the antenna 52a of the motion and presence sensor 52 are arranged on a common base board 520, which is applied to the front side A of the module board 8. The motion or presence sensor 52 and the antenna 52a of the motion and presence sensor 52 can thus be coupled to the module board 8 quickly and cost-effectively.

[0082] In another, in Figure 9shown embodiment of a lighting device 1ʺʺ, as in the in Figure 7 illustrated embodiment, all electronic components arranged on the module board 8 are arranged on its front side A. In contrast to the Figure 7 shown embodiment of the lighting device 1" are in the lighting device 1ʺʺ of Figure 9 The motion or presence sensor 52 and the antenna 52a of the motion or presence sensor 52 are arranged on a base board 520. The base board 520 is electrically connected to the module board 8.

[0083] In a further embodiment of the lighting device 1ʺʺ, it is also conceivable that, for example, the wireless communication device 7 and the antenna 7a of the wireless communication device 7, the brightness sensor 51 and / or the luminaire and / or luminaire driver control device 6 are arranged on at least one further base board which is electrically conductively connected to the module board 8.

[0084] Furthermore, in the Figure 9 shown embodiment of the lighting device 1ʺʺ the module board 8, unlike in Figure 7, is not electrically connected to the carrier board 2 via SMD pads 81, but via an electrical connection 15. The electrical connection 15 is embodied as a plug in the present case, but can also be configured differently in further embodiments of the lighting device 1. In the simplest case, the electrical connection is embodied as an electrically conductive cable, which is connected to both the module board 8 and the carrier board 2.
